Question

Stefan measured a weight of a package as 15.375 pounds. The actual weight of the package is 15.125 pounds.

What is the approximate percent error Stefan made in measuring the weight of the package?write ur answer to the nearest percent.
Part b
Alexis measured the weight of the same package and got the same percent error as Stefan. Alexis and Stefan both measured different weights of the package.
What weight in pounds did Alexis measure. Explain how u know

Answer 1

The formula is |(estimated - exact ÷ exact) x 100|

((15.375 - 15.125) / 15.125) x 100 = 1.652892562
You might want to round that number a 'lil

Part 2: She got 14.875 b/c with the equation there are no negative percentages, so that means that since 15.375 - 15.125 = 0.25, than 15.125-0.25 = what she got.
